With the Cubs in the playoffs this year, an old memory was jogged having to do with something called an ex-Cub factor. Someone came up with this silly idea that if you have 3 or more ex-Cubs on your team, then your postseason was doomed. It's a silly idea because you could pick almost anything that could doom a postseason run and you have a good chance of being correct since all but one of the teams participating will end without a championship.
However, the ex-Cub factor talk isn't really the memory that got jogged for me.
